  • Optical cursor tracking correction system
    Patent number: 4114034
    Abstract: Linear photosensitive array rotatably mounted in a digitizing cursor and maintained in an orthogonal relationship with the function (such as a curve or the like) to be digitized. As the cursor is moved along the function, the photosensitive array is maintained at right angles to the direction of the cursor movement. Circuits are provided to sense any difference in position between an indicium in the cursor and the function being traced, to obtain correction values to be applied to the digitized coordinates of the cursor position.
